Seems I was thumbing through a recent backissue and it made claim that the pci raid card was maxed out at three drives.
Indicating performance suffered upon adding the fourth drive, because the pci port was too small to handle the data capabilities of all four at once.

If correct, since I have the pci raid card (Fastrax tx) mentioned, with four drives in 0+1, I was wondering, how does one array three drives?

You could stripe as many drives as you want if the card supports it. With 3 drives you could also do RAID5 which is a stripe with 2 drives and the thrid drive used for parity. There are many different RAID arrays however the card needs to support them if you want to use them, and only the expensive ones handle some of the obscure arrays.

Is it possible to stripe across three drives?

If I recall correctly, the article you are talking about had all the drives as raid 0. You have 2 drives as raid 0, and 2 drives as raid 1, so I dont believe you are bottle necked like they were in the article moving from 3 to 4 drives.

So, with the Promise FastTrak TX100 TX (2 Channel) RAID card, and three Western Digital Caviar SE 80 Gig HD's on a striped array, I could have a 240 Gig Stripe and, even more unreal I/O speeds for my aplications (games), than having a four drive 0+1 Array?
This would mean no redundancy (no mirror), but it's just games and web surfing I use the computer for, not missions of state or national security.

Well then, since the card I have has only two channels, would having to connect two drives to one of them, and the third to a separate channel, create an 'imbalance', bottleneck, or other problem?
Two drives piped into one channel seems like it might be less effective than one drive per channel.
The port is unidirectional is it not, meaning that it can input or output, but not both at the same time.
One drive would have free reign, the other two would be waiting turns. it seems.
